Whenever I play a specific note on my MIDI keyboard, Live starts recording.

More specifically, when I play C7 on my keyboard, it records in whatever track and scene is selected. Have I accidentally bound this key to something? I am using the Novation Launchkey 49, in case that helps. I just increase the octave by 1 and the highest C on the keyboard triggers this. I have no idea why. If this is a keybinding issue, how should I go about undoing this? Thanks!
